A new protocol was developed to obtain a composite photocatalyst by incorporating indium to ZnO and subsequently assembling it with reduced graphene oxide (RGO) sheets. The incorporation of indium led to lattice distortion of ZnO and introduction of defect levels. The hybridization with RGO could improve the electron transport and extend the lifetime of photo-generated carriers, leading to enhanced activity for dye degradation driven by visible light. The photocatalytic activity appeared to be dependent on the relative quantity of RGO. The optimized quantity resulted in the highest activity due to the dual role of electron shuttle and "shielding effect" of RGO. In addition, the composite photocatalyst exhibited excellent repeatable use performance, suggestive of its high stability. This study proposed a promising strategy to construct photocatalysts by rational bandgap engineering and tunable composite technology.
